About this 1.19ct natural cushion diamond

This 1.19ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2225454766. Listed at 5 retailers as of October 31, 2026, with prices from £3,450 to £4,422, a £971 spread on the same certified stone. Cape Diamonds lists it at £4,422. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
